Since 1977, several boat builders in Brittany have built specialized amphibious vehicles for use in the area's [[mussel]] and [[oyster farming]] occupations. The boats are made of aluminium, are relatively flat-bottomed, and have three, four, or six wheels, depending on the size of the boat. When the tide is out the boats can run on the tidal flats using their wheels. When the tide is in, they use a propeller to move through the water. Oyster farmers in [[Jersey]] make use of similar boats. Currently, ''Constructions Maritimes du Vivier Amphibie'' has a range of models.<ref>{{cite web  |url=http://cmv-amphibie.com/en/ |title=Our projects |website=CMV Amphibie |access-date=13 May 2018}}</ref>
